MACHINEFORMAKING CRlMPlNG-FORMS..

SPECIPICATIONfdrming part of Letters Patent No. 301,581, dated July 8, 1884.

Application filed February 18, 1884.

To aZZ whom/it may concern.-

Be it known that I,-Jonn W, D. FIFIELD, of North Brookfield, county of W'orcester, State of Massachusetts, have invented an Improvement in Machines for Making Crimping- Forms, of which the following description, in connection with the accompanying drawings, is a specification, like letters on the drawings representing like parts.

This invention relates to that class of ma;

. chine represented in United States Letters Patent No. 281,856, granted to me July 24, 1 888, to which reference may be had, and has for its object the production of a machine containing fewer parts, andin which the sliding frames are adapted to he moved byhand, each independently of the other, in a very simple manner.

The particular features in which my invention consists will be hereinafter described, and specifically pointed out in the claims at the end of this specification.

Referring to thedrawings, Figure 1 represents a top or plauview of my improved machine, the crimpingrform being s'upposedto have been operated upon by the cutter-head and reduced or shaped to conform to the pat tern; Fig. 2, a side elevation of Fig. 1; Fig. 3, a left-hand end view of Fig. 1; Fig. 4, enlarged details of the clamp to hold the leg end of the form, and Fig. 5 enlarged details of the clamp for the foot of the form.

The frame-work A, of proper shape to receive the working parts, to be described, has at its top a track, A having, as herein shown, a projection, 3, which receives upon it and guides the base slide or frame B, provided with a track, 4, upon which the pattern and form-carrying slide D is made movable at right angles to the movement of the base-slide on the track 33. The shaft O, carrying the cutter-head O, substantially such as in my saidpatent, has its hearings in stationary boxes 0, attached to the frame-work A, and is rotated by a belt upon the belt-pulley c", and

the two frames referred to are so operated in unison, or one upon the other, as will behcreinafter described, as to present the wood to be cut, no matter what may be its particular outline, directly to the said cutter-head. A

(No model.)

the said shaft B may be rotated, but will not move longitudinally, and consequently as the shaft B is rotated in one or the other direction the base slide or frame B will be correspondingly moved in one or the other direction, and at a speed more or less rapid, according to the work being done. The slideframe D, mounted on suitable tracks, 4, of the slide 13, has attached to it by screws 5 the pattern d, and to another part of the said frame D, by devices to be described, is attached in an adjustable manner the piece of wood to be cut or reduced by the cutter-head c for the production of a boot or shoe crimping form, f. The leg part of the piece of wood to be'made into a crimping-formj, will be engaged by spurs cc of a spur bar or dog, 6, held in a guide-block, ehattached by bolt c to a bar, 6 provided with a longitudinal i-shaped groove, in which is placed the head of the said bolt, as shown in Fig. 3,1311: said bar being secured to the slide-frame D, the said dog being adjustable on the. block by the not 6 on its threaded end, and by the screw 7, the latter forcing the spurs in the wood. The plate 1, attached to the frame D by bolt is provided with a clamp-rod, 9 having a suitable spur, 9 adapted to enter and hold the toe end ,of the piece of wood to be cut into shape for the form f. An adjustable plate, It, attached to the plate 6 by suitable screws, is adapted to rest against the rear side of the said piece of wood, as in Fig. 1, to brace the same between its ends when being acted upon by the cutterhead. The piece of wood to be made into a crimping-form will be sawed out into nearly the outline which it is to have when finished, and connected, as described, with the frame D, it will partake of the movements of the latter, and the edge of the said piece of wood will be presented to the cutter-head, and will be beveled, as usual, along the leg and foot part from end to end. The frame D has a connected rack, 10, which is engaged by a gear, 12, on a shaft, 13, having-its bearings 14 fixed in a stationary part of the frame-work, and pro vided with a suitable handle or crank, 15. The stationary part of the frame is provided with a guide, m, preferably a roller on a fixed stud. Rotation of the shaft 13 in one or the other direction correspondingly moves the frame D, and while partaking of these moven1ents,or while stationary on the frame B, the latter may be moved in one or the other di rection parallel with the shaft B WVhen the cutter-head is to act and form and bevel the edge of the crimping-form, the frame D will be in such position with relation to the cutterhead 0 as to enable the latter to act upon thepiece of wood to be cut at its leg end, and substantially at the point 20, and the point 22 of the pattern d will then occupy a position against the guide m. The cutter-head having been started, the shaft 13 will be turned to move the pattern d away from the cutter-head, the pattern traveling with its edge against the guide at until the latter arrives at the point 24, at which time the cutter will have cut the form to the point 23. Thereafter both shafts 18 and B will be moved more or less, thus moving the two frames D B in such direction as to keep the foot-shaped edge of the pattern against the guide m, which movement will re-' sult in presenting the form f correctly to the cutter-head, the latter, as it finishes the form, passing from it, as shown in Fig. 1.

I have described the machine herein referred to as especially adapted to shape boot and shoe crimping forms; but I desire it to be understood that the described mechanism will 1 cut a piece of wood to correspond in outline with that of the pattern d, whatever may be its shape, as will be obvious to any worker of wood.

I claim v 1. The combination, substantially as shown and described, in a wood-molding machine, of the frame A,having transverse tracks, the baseslide B, mounted thereon and connected with a traversing screw, 13 the slide D, mounted on longitudinal rails on the base-slide, and movable by a rack and pinion lengthwise of said crosswise-moving frame, the pattern d, attached to the slideD, the guide-roller m,'the clamping devices for. holding the wood to be molded on three sides, and the fixed rotary. cutter acting upon said wood as it is presented to it under the direction of the pattern and roller, as specified.

2. In a wood-molding machine, the combination, with the pattern and its slide or frame, the fixed rotary cutter, and the movable baseframe, of the wood-holding devices consisting of thebar e on theslide-frame, the bar e, provided with spurs to engage one end of the wood, the guide-block e for said bar, adjustably connected to the bar 6', the adjusting devices 6 7 for said bar, the clamp-rod 9 provided with spur g toengage the other end of the wood, and the back bar, h, all substantially as shown and described.

In testimony whereof Ihave signed my name to this specification in the presence of two subscribing witnesses.
